Abstract: A contacting system for producing an electrical connection between a primary device and a secondary device, comprising a primary transmission element with multiple primary contact surfaces; and comprising a secondary transmission element with multiple secondary contact surfaces. Furthermore, the primary transmission element has multiple primary PE contact surfaces and the secondary transmission element has at least one secondary PE contact surface. An electrical connection between the primary device and the secondary device is produced by contacting of the primary transmission element and the secondary transmission element.

Abstract: A vehicle connection device for electrically connecting a vehicle contact unit to a ground contact unit of an electric charging infrastructure has the vehicle contact unit, a pneumatically operated contacting actuator adapted to move the vehicle contact unit, and at least one air outlet for blowing the ground contact unit free, the vehicle contact unit including a base having a contacting area facing the ground contact unit and having at least two electrodes, and the at least one air outlet for blowing the ground contact unit free being directed to a region in front of the contacting area, the compressed air for operating the contacting actuator being guided to the air outlet in order to blow the ground contact unit free. Further, a vehicle connection device having a guide device and a vehicle connection system are shown.
